The role of sleep in aesthetic perception and empathy: A mediation analysis.

The ability to experience aesthetics plays a fundamental role in human social interactions, as well as the capacity to feel empathy. Some studies have shown that beauty perception shares part of the neural network underlying emotional and empathic abilities, which are also known to affect sleep quality and duration. In this study, we evaluated for the first time the effects of sleep on the relation between aesthetic perception and empathic abilities in healthy subjects using a mediation analysis approach. One-hundred and twenty-six subjects participated in this study. One-hundred and one subjects slept at home (Sleep Group). The remaining 25 subjects were tested as controls after 1 night of sleep deprivation to assess the effects of lack of sleep on aesthetic perception and empathy (Sleep-Deprived Group). All participants underwent one testing session in which they performed a battery of empathy tests and an aesthetic perception task (Golden Beauty). The results showed that sleep duration mediates the relationship between empathy and aesthetic perception in the sleep group. The mediation effect of sleep was more evident on the emotional empathy measures. Conversely, in the sleep deprivation group the lack of correlations among empathy, aesthetic perception and sleep variables did not allow to perform the mediation analysis. These results suggest that adequate sleep duration may play a significant role in improving cognitive and emotional empathic abilities as well as the capability to give accurate aesthetic judgements.

Discrepancies between explicit and implicit evaluation of aesthetic perception ability in individuals with autism: a potential way to improve social functioning.

BACKGROUND: The capacity to evaluate beauty plays a crucial role in social behaviour and social relationships. It is known that some characteristics of beauty are important social cues that can induce stereotypes or promote different behavioural expectations. Another crucial capacity for success in social interactions is empathy, i.e. the ability to understand and share others' mental and emotional states. Individuals with Autism Spectrum Disorder (ASD) have an impairment of empathic ability. We showed in a previous study that empathy and aesthetic perception abilities closely related. Indeed, beauty can affect different aspects of empathic behaviour, and empathy can mediate the aesthetic perception in typically developing (TD) individuals. Thus, this study evaluates the ability of aesthetic perception in ASD individuals compared to TD individuals, using the Golden Beauty behavioural task adapted for eye-tracking in order to acquire both explicit and implicit evidences. In both groups, the relationship between empathic and aesthetic perception abilities was also evaluated. METHODS: Ten ASD individuals (age ± SD:20.7 ± 4.64) and ten TD individuals (age ± SD:20.17 ± 0.98) participated in the study. Participants underwent empathy tasks and then the Golden Beauty task. To assess differences in the participants' performance, we carried out a repeated measures general linear model. RESULTS: At the explicit level, our behavioural results show an impairment in aesthetic perception ability in ASD individuals. This inability could have relevance for their ability to experience pleasure during social interactions. However, at the implicit level (eye-tracking results), ASD individuals conserved a good ability to feel aesthetic pleasure during the Golden Beauty task, thus indicating a discrepancy between the explicit and implicit evaluation of the beauty task. Finally, beauty perception appears to be linked to empathy when neither of these capacities is compromised, as demonstrated in the TD group. In contrast, this link is missed in ASD individuals. CONCLUSION: Overall, our results clearly show that individuals with autism are not completely blind to aesthetic pleasure: in fact, they retain an implicit ability to experience beauty. These findings could pave the way for the development of new protocols to rehabilitate ASD social functioning, exploiting their conserved implicit aesthetic perception.

Exploring the social cognition network in young adults with autism spectrum disorder using graph analysis.

BACKGROUND: Autism spectrum disorder (ASD) is characterized by an impairment in social cognition (SC). SC is a cognitive construct that refers to the capacity to process information about social situations. It is a complex network that includes distinct components. Exploring how SC components work together leads to a better understanding of how their interactions promote adequate social functioning. Our main goal was to use a novel statistical method, graph theory, to analyze SC relationships in ASD and Typically Developing (TD) individuals. METHODS: We applied graph theory to SC measures to verify how the SC components interact and to establish which of them are important within the interacting SC network for TD and ASD groups. RESULTS: The results showed that, in the TD group, the SC nodes are connected; their network showed increased betweenness among nodes, especially for the Theory of Mind. By contrast, in the SC network in the ASD group the nodes are highly disconnected, and the efficient connection among the components is absent. CONCLUSION: ASD adults do not show SC competencies and functional communication among these skills. Under this regard, specific components are crucial, suggesting they could represent critical domains for ASD SC.

Understanding criminal behavior: Empathic impairment in criminal offenders.

Criminal offenders (CO) are characterized by antisocial and impulsive lifestyles and reduced empathy competence. According to Zaki and Ochsner, empathy is a process that can be divided into three components: mentalizing, emotional sharing and prosocial concern. The aim of our study was to evaluate these competences in 74 criminal subjects compared to 65 controls. The CO group demonstrated a lower ability in measures of mentalizing and sharing, especially in recognizing the mental and emotional states of other people by observing their eyes and sharing other people's emotions. Conversely, CO subjects showed better abilities in prosocial concern measures, such as judging and predicting the emotions and behavior of other people, but they were not able to evaluate the gravity of violations of social rules as well as the control group. In addition, logistic regression results show that the higher the deficits in the mentalizing component are, the higher the probability of committing a crime against another person. Taken together, our results suggest that criminal subjects are able to judge and recognize other people's behavior as right or wrong in a social context, but they are not able to recognize and share the suffering of other people.

The Role of Theory of Mind on Social Information Processing in Children With Autism Spectrum Disorders: A Mediation Analysis.

Individuals with autism spectrum disorders (ASD) show significant impairments in social skills and theory of mind (ToM). The aim of this study was to evaluate ToM and social information processing abilities in 52 children with ASD compared to 55 typically developing (TD) children. A mediation analysis evaluated whether social information processing abilities can be mediated by ToM competences. In our results, children with autism showed a deficit in social skills and ToM components. The innovative results of our study applying mediation analysis demonstrate that ToM plays a key role in the development of social abilities, and the lack of ToM competences in children with autism impairs their competent social behavior.

Simple Mindreading Abilities Predict Complex Theory of Mind: Developmental Delay in Autism Spectrum Disorders.

Theory of mind (ToM) is impaired in individuals with autism spectrum disorders (ASD). The aims of this study were to: (i) examine the developmental trajectories of ToM abilities in two different mentalizing tasks in children with ASD compared to TD children; and (ii) to assess if a ToM simple test known as eyes-test could predict performance on the more advanced ToM task, i.e. comic strip test. Based on a sample of 37 children with ASD and 55 TD children, our results revealed slower development at varying rates in all ToM measures in children with ASD, with delayed onset compared to TD children. These results could stimulate new treatments for social abilities, which would lessen the social deficit in ASD.

Investigation on quality of life and psychological well-being of citizens of L'Aquila after earthquake on April 6, 2009.

PURPOSE: In April 2009 there was an earthquake in L'Aquila city. Several studies have shown that the citizens ability to react to a stressful situation is related to the satisfaction level of services during the reconstruction process of the city. The general aim of the present study is to investigate if the knowledge of information about the reconstruction phase has an influence on the satisfaction of the citizens, regarding the lifestyles and the capacity to adapt and respond to changes. MATERIALS AND METHODS: Five hundred and three residents in L'Aquila city were interviewed using a questionnaire that examines the satisfaction level, understanding of political issues and the resiliency skills of individuals. Results: The data show that the lack of information about the work of the facilities of by the Government has caused dissatisfaction among the citizens who feel that they have not been well informed about the rebuilding on the city. CONCLUSION: The study can represent an indication concerning the facilities and assistance provided by politicians and be understood as an input in order to improve the administrative system and public welfare.
